Doppler frequencies generated by the navigating ship targets may coincide with the first order Doppler spectrum of the sea clutter in high frequency surface wave radar (HFSWR). Therefore, the ship targets fall in this clutter spectrum were usually undetectable by the traditional processing method in HFSWR. In this paper, we introduced a spatial blind filtering method based on oblique projection, which...
Traditional approaches for interference suppression will enjoy the added benefits when more domains are involved in antenna array. However, the information from range domain and its collaboration with other domains are rarely explored, and their potentials in improvement of radar performance are under-estimated. In this paper, we introduce the concept of polarization sensitive frequency diverse array...
As a non-contact automatic identification technology, radio frequency identification (RFID) technology plays an increasingly important role in social life. But the existence of potential safety problems has restricted the widespread application of RFID technology. In order to deal with the design challenges in the calculation of speed, communications capability and storage space to the low-cost radio...
Both spectrum sensing and intelligent access of the secondary user (SU) are key technologies for cognitive radio. This paper focuses on a novel setting and access control method of adaptive sensing threshold based on power detection of the primary user (PU), on the basis of the analysis of the coexistence model between PU and SU. Mathematical and practical numerical simulations confirm the good performance...
It is essential to do the evaluation on road passenger transportation enterprise's industrial safety impersonally, scientifically and rightly at present in order to reduce the traffic accident in China. This article establishes the industrial safety evaluation index system for road passenger transportation enterprise based on the rule of ministry of transport of the People's Republic of China and...
In order to realize the differentiated mechanism of mesocarp and endocarp in stone fruits, the profiling of protein expression in mesocarp and putamen of peach were analyzed by two-dimensional electrophoresis (2-DE) to explore the whole cellular milieu of proteomic variety. Peach fruits around 60 days after anthesis were adopted in this observation. The total protein was extracted by TCA/ cold acetone...
Gold nanotubule membranes were prepared by using electroless deposition of gold in the pores and on the surfaces of polycarbonate track-etched membranes, and the membranes were modified with Cl − . An electrochemical method (i–t) was then developed for studying the transport properties of bovine serum albumin (BSA) in these nanotubule membranes. In phosphate buffer solution (pH 7.4), when...
